Need to replace the transmission in my van.I can't find one the same from the same vehicle. Is there another vehicle donor I can use?
Thanks, Mark

There are many to choose from because they use the same transmission is GM cars of that year. If you you need more info wrecking yards have special software that tell precisely what cars will work.

Here is a video of the job being done on a similar car, the process is the same.

Please let us know if you need anything else to get the problem fixed.

Hi Mark,

I ran a quick search and seem to have the same issue you are. Is there any way you can just have it rebuilt? Most transmission shops will do this for about the same price as a replacement.

Also, I would suggest searching for your specific transmission, 4L80E or 4L85E and you will find some options but none that fit your specific vehicle. This is usually because it is not a "bolt in" option. But if you change out a mount or bracket then it could fit. Basically, just call the company that is selling it and find out what the difference is because the inside of the unit is the same.

Hope this helps.
